27 Claims.

This invention relates to manifolding books, pads and the like, and is specially concerned with the kind in which each manifolding set in the book has one or more carbons which are indi- 5 vidual to such set.

One of the most important objects of this invention is the provision of a manifolding salesbook having a number of manifolding units or manifolding sets, each unit including one or 10 more carbon sheets individual to it and separate from the carbon sheets of other units so that in manipulating the book contact with the carbon is practically entirely avoided. a

A further important object is the constructionv of such a book which will lend itself to the utilization of a large number of carbon sheets of relatively thin material having a relatively light coat of carbon and constructed so as to conserve and protect the carbon leaves at all times.

N Other important objects of the invention arethe provision of a simple and practical book structure, or book element, which may be used to make up manifoldnig books or pads designed to furnish either two or three, or any practical number of copies at one writing; the provision of a simple, convenient and eflicient means for facilitating the ultimate manual stripping or separation of the transfer leaves or carbons, from the record leaves; the provision of a practical arrangement wherewith a copy of the record may automatically be retained in the book though others of the records be torn out; the provision of a simple and eflicient construction and arrangement of the leaves lending itself to covering the many carbon leaves employed and guarding against smudging by the carbon leaves; the provision of a practical and simple construction for holding the sheets of each manifolding unit, or manifolding set, in superposed registry and protecting the operator against contact with the carbons while inscribing and while operating the book; the provision of a practical and relatively inexpensive book in which the leaves may id colors of paper, and the provision of a simple construction of book giving practically perfect copies, and a book which is adapted for very rapid operation.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exem- 5 plified in the article hereinafter described and be of different qualities of paper or of different the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

Fig. 1 is a perspective view of a manifolding salesbook embodying the invention and adapted for the making of four copies at one writing, namely, an original and three carbons;

Fig. 2 is a view showing two of the manifolding units or manifolding sets of Fig. 1 diagrammatically and with the leaves separated for clearer disclosure;

Figs. 3 to 12 inclusive are diagrammatic views similar to Fig. 2 but illustrating modified constructions of salesbooks embodying the invention;

Fig. 13 illustrates one of the carbon leaves, showing its clean end I5; and

Fig. 14 illustrates one of the carbon leaves having a notch permitting selective gripping.

In respect to all of the above figures, it is to be understood that similar reference numerals refer to similar parts throughout the several views.

Referring now more specifically to the drawings, and particularly to Figs. 1 and 2, a plurality of main manifolding units are associated in superposed relation to each other, the several units being bound together at the stub end of the book, each manifolding unit comprising a plurality of leaves. In Fig. 1 one of the manifolding units is illustrated in detail with the leaves widely separated from each other for clearer disclosure. It is to be understood that the book of Fig. 1 includes a plurality of these manifolding units in superposed relation to each other.

Referring more specifically to the construction of Fig. 1, each manifolding unit comprises a plurality of record leaves I, 2 and 3, and two transfer sheets or carbon leaves 4 and 5, these five leaves being in superposed manifolding relation to each other and unitedtogether, as indicated at 6, outside the bound end of the book, and adapted for detachment as one from the book. The leaves may be united together at their ends remote from the bound end of the book by any suitable and practicalmeans. In the embdiment illustrated, these'leaves of the unit are pasted together, the carbon sheets having clean margins l for being pasted between the record leaves. Of course, the separate leaves might be stitched or stapled together at the ends 6. Viewed in some aspects of the invention, one or another of these leaves might be an integral foldof an underlying leaf of the unit. In the book of Figs. 1 and 2, the top leaf and the bottom leaf of each unit are not only pasted to the other leaves at their ends 6 remote from the bound end of the book, but these top and bottom leaves are also bound in the book at the stub end thereof, the bound ends of these leaves being indicated at I and 8.

For ready detachment from the bound end of the book, each of the bound leaves is provided with a weakening line 9, these weakening lines in the different leaves being in superposed registry with each other.

Each of the carbon leaves 4 and in each unit has its edge portion or free end l l displaced from the adjacent edges I2 of the record'leavesofthe unit (which would be formed by detachment of the record leaves along the weakened lines 9) to provide a selective grip area in the unit, at which area the record leaves of the unit, when tornirom. .the bound endof the book, ,may be gripped by the operator without gripping the carbon leaves. The point in each unit-at which the selective grip areais provided is remote from the union of the carbons to-the other leaves. Betweentheunited ends .6 of therecord leaves and the selective grip area just referred to, the recordleaves have weakened transverse parting lines, indicated at M; in superposed registry with each other. Although the intermediate carbon leaves l and- 5 may also be-weakened in superposed registry with the parting lines-i4,- it is preferred that they-remain .unweakened along such. lines so that they arenot so readily parted along such lines as are the record leaves.

In the embodiment illustrated in Figs. 1 and 2, the carbon-leaf l is asingle face carbon leaf, soas to transfer inscription to the bottom record leaf 3-of the unit without imprinting the back of the intermediaterecord-leaf 2; immediately thereabove. Of course, a double face carbon leaf 4 may-be utilized, if desired. The carbon leaf 5 is -a double face carbon leaf so as to-transfer the inscription to thetop face of the underlying record leaf 2 of the unit-and also to transfer the inscription to-theunder face of a supplemental record leaf [7, this supplemental leaf being bound in the book at the-stub end and having its opposite end lyingto one side of-the union 6 of the other record leaves of the'manifolding' unit, so as ordinarily not to be grasped when the end 6 is grasped. In this wise, outer or free end of the supplemental leaf I! need not be grasped when the pasted ends'fiof the other-leavesare grasped for tearing the latter from the book along the weakening lines I 9.:-

It is to be understood that for-each main manifoldin -unit of the book of Figs.- 1 and 2, there is a separate-supplemental lea-f: II, these supplemental leaveslying in interleaved relation in their respective: units and being attached to the book so astombe retained therein after detachmenttof the main mani-foldingunits fromthe book. As'il'lustrated in Figs. 1 and-2, the supple- -mental leaves-l1 are bound in .the stub of the book along withthe other bound leaves, and they lie between the :bound and united record IGaVBSlIlthe. respective units; In-usual practice, the supplemental .record leaves are of translucent material, .as'for instance: tissue paper, so that the record made on the bottom face theresupplemental leaf H.-

book after the main manifolding units have been detached, and in such circumstances the supplemental leaves need not have any transverse weakening lines along which they may be detached from the stub end of the book. However, weakening lines in the supplemental leaves for detaching purposes may be provided, if desired, as illustrated, for instance, at l9 (Figs. 1 and. 2). Also, in Figs. 1 and 2, the record leaves I, 2 and 3 are usually of opaque paper, so that three direct reading records are obtained on durable, opaque paper, the fourth record being ordinarily on the bottom face of the translucent or tissue leaf: 11; If desired; and to accommodate special conditions, the supplemental leaf ll may also be made of opaque paper, in which case an additional carbon leaf might be included in each main manifolding set for transferring to the upper face of the opaque supplemental leaf. Or if the indirect-reading on the bottom of the opaque supplemental leaf were satisfactory, said additional carbon leaf'need not be employed.

Inasmuch'as each .manifolding unithas one or-more of its .own individual carbon leaves, inscription on one of the upper units has a tendency toebe-transferredto the underlying units. In order to avoid transferring to underlying units, a stop; or stop card or sheet, may be interposed between the-:unit being. inscribed and the one lying therebetween. This stop card may-be conveniently provided by airelatively thick manila sheet or card-20, which may be an integral extension of a backingor backZl in which the several manifolding'units composing the book are. assembled and-held or bound together, as for instance by the staples 22, which pass through a folded end of the backing and the stub ends of the bound leaves hereinbefore mentioned. It is to be understood, however, that any practical device for preventing transfer of inscription from one manifolding set to the other may be employed; as. for instance, it may-bedesirable at times to have the bottom leaf3 of each manifolding set made of'a thickness and substance to serve as the stop.

The book of Figs. 1 and 2 may be operated as follows:

It' will be understood that the record leaves of the book will usually have printed forms thereon. and'that these printedforms will be held in superposed registry because all the leaves are united together, as by the pasting at 6. Having interposed the stop,.card 28 between the manifolding unit to be inscribed and the next underlying unit, the inscription is made. Thereupon, theinscribed manifolding set is grasped at its free end 6,,without grasping the adjacent end of the'supplementalleaf l1, and the main manifolding set may then be readily torn from the book, the bound leaves readily parting along the weakening lines 9, closely, adjacent the stub of the book. The separated or single manifolding set thus produced will have the carbons in position for causing any further inscription to be transferred to the underlying leaves of the separated unit. Th'us, although'the main manifolding unit has been parted from the book, it is still in condition for manifolding'inscription, andthe record leaves with printed forms are still held in superposed, accurate. registry. For stripping, i.

r e., separating; the carbons from the record leaves of the inscribed manifolding'unit, the united ends of theleaves aregrasped by one hand of the operator'at 6, andatthe opposite 'end, or selectivegrip area, by the other hand, .whereupon to h except ,ject being firmly to secure by either a snapping action separating the ends, or a tearing action, the record strips will be parted along the lines l4, l5 and I6, and the carbon leaves will remain attached to the pasted i union 6 and be drawn from between the record leaves with said detached pasted portion. Thus, in this manifolding book or pad, each manifolding unit is readily torn from the bound end of the book without tearing out the supplemental leaf l1, and thereafter the carbons ofthe tornoff set are readily removed as one from the record leaves by a simple operation. In the book illustrated in Figs. 1 and 2, the manifolding units are bound to each other by staples 22. It is to be understood, however, that any suitable means may be employed for attaching the manifolding units together in the book, as for instance textile thread stitching of various sorts, pasting, impaling pins and the like, the obthe units together at the bound end of the book.

It is to be understood that the invention. may be embodied in manifolding books designed for themaking of either two or three copies at one inscription, or for the making of either five or six, etc. copies at one inscription. It is also to be understood that the invention may be embodied in manifolding books of different specific construction from the quad book illustrated in Figs. 1 and 2. For instance, a modified book is diagrammatically illustrated in Fig. 3. The construction of the book of Fig. 3 is exactly similar to the construction illustrated in Figs. 1 and 2, except that the intermediate record leaf 23 is .not bound in the stub of the book, but its end 24 terminates in superposed registry with the weakening lines 9 in the record leaves I and 3.

Fig. 4 illustrates a book corresponding in construction with the book of Figs. 1 and 2, except that it is designed for the making of but three copies at one writing, and hence each manifolding unit includes only two record leaves and 3! and only one carbon leaf 32 pasted together at their ends 6 remote from the bound end of the book, the carbon leaf 32 being double faced. In the book of Fig. 4 there is a supplemental leaf I! in each unit corresponding to the similar unit in Figs. 1 and 2.

The book illustrated in Fig. 5 corresponds in all respects to the book illustrated in Fig. 4, that the supplemental record leaf I1 is omitted, and hence but two copies are made at one writing, an original and a duplicate.

In the modified book diagrammatically illusg.;trated in Fig. 6, the construction is similar to that in Fig. 5, except that the carbon in each the carbon leaf manifolding unit is bound into the stub of the book as indicated at 4|, its opposite end being free from the union 6 between the original record leaf 42 and the duplicate record leaf 43.

Fig. 7 illustrates a still further modification over Figs. 5 and 6 in that the carbon leaf is not only united tothe original record leaf 5| and the duplicate record leaf 52 at their ends 6, as described in connection with the other figures, but 50 is also bound into the stub of the book, as illustrated diagrammatically at 53. The carbon leaf 50 of this particular arrangement is preferably provided with a weakened line 54 in superposed registry with the weakened lines 9 in the record leaves, so that both the record leaves and the carbon leaf may readily be detached from the stub of the book as a unit. Inasmuch as the free ends of the detached, multi-ply manifolding unit of, Fig. 7

are in substantial superposed registry with each other, the carbon leaf 50 may be provided with a cutout, notch or the like, as indicated at 55 (Fig. 14), so that the free ends of the record leaves 50 and 52 may be grasped at their corners, without grasping the carbon sheet 50, and the carbons stripped from between the record leaves 5| and 52 by tearing off the pasted margin 6 as hereinbefore explained, in connection with Figs. 1 and 2.

Fig. 8 diagrammatically illustrates a modified construction similar to Fig. 4, but in which the carbon sheet is! unattached and lies loosely between the record leaves 6| and 62, which latter are each bound in the stub of the book and also united at 6, as before explained. The carbon sheet 60 is double face to make inscription on the under face of the supplemental leaf l1 and the upper face of the duplicate record leaf 6|. In the book of Fig. 8, inasmuch as the carbons are free, the carbon sheet may be coated fully thereover and the record leaves 6! and 62 need have no weakening lines adjacent the union 6 with each other, except for being separated from their union 6.

The book diagrammatically illustrated in Fig. 9 is generally constructed like the book of Figs. 1 and 2, but all the record leaves of each unit are not bound in the stub of the book. As illustrated in Fig. 9, the original record leaf Hi, the duplicate record leaf 1 I, and the triplicate record leaf 12, are united to each other at their ends 6 remote from the stub of the book, carbons 13 and 14 being also interposed therebetween and united therewith, as explained in connection with Figs. 1 and 2. Also, Q each unit a supplemental leaf 15 corresponding to supplemental leaf l'! of Figs. 1 and 2 is employed. But

in Fig. 9 only one main record leaf 12 is secured in the stub end of the book. The record leaves 10 and II are enough longer than the carbon leaves 13 and 14 to provide the selective grip areas at the ends of the record leaves, as hereinbefore explained, the free ends of the record leaves 10 and II terminating in registry with the weakening line 9 along which the bound record leaves 12 may be detached from the stub of the book. Also the record leaves 10, H and 12. each has the weakened line 14 adjacent their union 6, the carbon leaves preferably being unprovided with weakening lines in registry with the lines I4. Both Figs. 1 and 2, and Fig. 9, illustrate quad books, the book of Fig. 9 being modified over Figs. 1 and 2 in the particulars noted.

The book of Fig. 10 is similar in construction to that of Fig. 9, except that as it is designed for making only three copies at one writing, the supplementary leaf 15 of Fig. 9 is omitted. Otherwise, the construction may be similar to that of Fig. 9 and include an original record leaf to, a duplicate record leaf BI and a triplicate record leaf B2 pasted at 6 to the clean ends of the carbon leaves 83 and 84, the carbon leaf 83 being a single face carbon as distinguished from the double face carbon 13 of Fig. 9. In the book of Fig. 10,'the duplicate and original record leaves 89 and 8| are not bound in the stub, whereas the triplicate record leaf 82 is so bound and has a weakening line 9 for detachment from the stub.

In the modification illustrated in Fig. 11, the construction is similar to that of Fig. 10, only one leaf being bound in the stub, except that inasmuch as only a duplicate and an original are required in each manifolding unit, one of the record leavesandone of the carbonleaves of Fig. 10 are omitted. Each manifolding unit in the book of Fig. 11 includes an original record leaf '9 0, a duplicate record leaf 9|, and an intermediate, single face carbon leaf '92, having a clean end 93, unitedtogether at 6, as heretofore explained.

In the book of Fig. 12, which is designed for making triplicate copies,-a supplemental record leaf lift, corresponding to leaf I! of Figs. land 2, is disposed in each manifolding unit between an original record leaf I ill and a duplicate record leaf 02, the original and duplicate being united to the intermediate carbon Hi3 at their ends 8,

as before explained, the carbon leaf Hi3 being double face for transferring inscription both to the triplicate leaf H32 and the face of the supplemental leaf 19%]; The record leaf N12 is bound in the stub and has a weakened line 9 for detachment from the stub, whereas the record leaf it! has a free end terminating in substantial registry Withthe weakened line of the leaf N12. The supplemental leaf 'i at is preferably to be retained in the book, but-may be provided with a weak- ,ened line act for detachment from the book,

if desired.

It'is to be understood thatthe books illustrated diagrammatically in the figures of the drawings are each constructed along the line as :described in connection with Figs. 1 and 2, except that the book and the manifolding units thereof are ofmodified construction as described in connection with the several diagrammatic figures.- In respect to each modification, it is to be understood that when th'e'several manifolding units or rrggnifoldingsets are assembled in superposed relation, they will preferably beenclosed in a backing simila-r to that described in connection with Figs. 1- and-2, and each will .also be equippedwitha stop card as hereinbefore explained. Inconnection with any of the modifications, it is to' beunderstood that the different uni-ts may be bound in the-book by staples,- textile threads, pasting or-the like, and that the several'leaves may be-united together outside the bound end of the book in-any suitable manner, as by textile stitching, or pasting, pasting being preferred andillustrated herein.

In'the preferred construction, and especially when each manifolding unit includes three or more leaves, the'pasting' of the leaves together outsidethe bound end of the book as indicated at 6 provides eachmanifolding unit with a relatively stiff end margin whichmay be used'as a handle in manipulating the unit. In each of the record leaves-the weakening lines M separate the stiff margin or handle from thebody of theleaf, thus providing for the removal of this relatively stiifhandlefrom themanifolding unit when desired.

Since-certain changes may be made in the above article and difierent-embodiments. of the invention could be made without departing from the scope thereof, it is .intended thatall matter ,containedin the above description or shown in the accompanyingdrawings shall be interpreted. as illustrative and not in a limiting sense.
